Optimization Study of the Air Passage of the House-hold Dehumidifier
摘要
Abstract
The outflow air passage of the house-hold dehumidifier was studied using CFD and experiment setup. The influences of radius of stabilizer and expansion angle of outlet on flow rate and noise were presented. The results show that an appropriate larger radius of the stabilizer can reduce the collision loss of airflow in the stabilizer, and a proper expansion angle of the outlet is helpful to reduce the separation loss at the outlet. Meanwhile, airproof enhancement in the inlet and fan is beneficial for reducing the noise and increasing the flow rate. The results can be applied to the practical design of dehumidifier.关键词
